Otitis media with effusion in children: Cross-frequency correlation in pure tone audiometry.
2019
Different guidelines are adopted in clinics and countries to assess pure tone hearing sensitivity in children with otitis media with effusion (OME). Some guidelines specify a broad range of audiometric frequencies that must be tested and from which average thresholds determined, while others leave test frequencies unspecified. For guidelines that suggest specific frequencies there are various pure tone frequencies and frequency ranges given. The present study investigated whether (1) a full range of audiometric frequencies is required to evaluate hearing loss caused by OME in children, or if neighboring frequencies provide essentially the same threshold information, and (2) if different com…
Changes in hearing in 80-year-old people: a 10-year follow-up study
2004
The aims of this prospective 10-year longitudinal population study were to report changes in hearing in people aged 80 years at baseline, and to assess such changes by comparing results from both cross-sectional and longitudinal analyses. The study population comprised all residents of the city of Jyväskylä born in 1910 (n = 291). The subjects' hearing was tested on three occasions at 5-year intervals with the use of pure-tone audiometry, speech audiometry, and self-report on hearing difficulties. The results showed a significant deterioration in hearing sensitivity in both the longitudinal and cross-sectional assessments over the 10-year follow-up. However, the change in self-assessed hear…
Evoked otoacoustic emissions and pure tone threshold audiometry in patients receiving cisplatinum therapy.
1993
Eight children and young adults with cancer were evaluated serially using pure tone audiometry as well as registration of click-evoked otoacoustic emissions (EOAE) 1 day prior to therapy as well as after various numbers of doses of cisplatinum. A reduction of EOAE-amplitudes following cisplatinum therapy was observed in all patients. This reduction tended to recover after the end of cisplatinum administration. Since EOAE are believed to result from cochlear bio-mechanical processes, the reduced emissions are interpreted as signs of cochlear dysfunction. We conclude, that EOAE testing may be a simple, non-invasive method that may detect early, transient functional impairment of hearing due t…
Transient evoked otoacoustic emissions in vestibular neuritis.
2007
Objectives: Partial or total degeneration of the vestibulocochlear anastomosis at its takeoff from the saccular ganglion and regenerating efferent neural buds under the cochlear outer hair cells (OHCs) have been found in the temporal bones of human patients with a history of vestibular neuritis (VN). We sought to test whether VN has any functional impact on the ipsilateral OHCs by means of transient evoked otoacoustic emission (TEOAE) testing. Methods: We retrospectively analyzed prospectively collected TEOAE data of 28 patients (19 female, 9 male; age range, 21 to 60 years; median age, 42.5 years). The pure tone air conduction hearing thresholds at each standard audiometric frequency (0.12…
[Difficulties understanding compressed speech in elderly listeners with mild-to-moderate hearing loss].
2007
Objective In this work we evaluated the difficulties in understanding rapid speech (normal, fast and very fast rates) in elderly listeners with and without hearing loss (presbycusis and moderate hearing loss). Rapid speech is common in daily communication, yet few studies have been conducted to assess this problem in Spanish-speaking listeners, as has been done for English speakers. Material and method We compared the recognition of sentences presented at normal, fast, and very fast speech rates in 3 groups of listeners. Recognition scores were correlated to their audiological measures and the score obtained on a Communication Difficulties Questionnaire. Results Compressed sentences were mo…
Genetic and environmental influences on hearing at different frequencies separately for the better and worse hearing ear in older women
2007
The purpose of the present study was to examine the relative contribution of genetic and environmental effects on the air-conducted hearing threshold levels at low (0.125-0.5 kHz), mid (1-2 kHz), and high (4-8 kHz) frequencies separately for the better and worse hearing ear in older women. We also examined the distribution of audiogram configurations. Data was analysed using quantitative genetic modelling. As part of the Finnish twin study on aging (FITSA), hearing was measured in 103 monozygotic and 114 dizygotic female twin pairs aged 63-76 years. Approximately every third subject had a flat type, and two-thirds a descending type of audiogram configuration. No significant difference was o…
Pure-Tone Thresholds, Speech Understanding, and Their Correlates in Samples of Men of Different Ages1
1986
Pure-tone thresholds and speech understanding were studied in three samples of men of different ages (31-35, 51-55 and 71-75 years). The air-conducted pure-tone thresholds were measured at 125-8,000 Hz and speech understanding by the help of interrupted and masked speech tests. The audiological measures were related to measures of other sensory functions, psychomotor speed, cognitive functions, psychic well-being, occupational and educational background and health. The results indicated a clear decrement in all audiological measures when proceeding from younger to older age groups. The results of the speech-understanding tests correlated significantly with the pure-tone thresholds both at 4…
An automatic test for frequency discrimination
1987
Békésy audiometry has been applied to the determination of the frequency discrimination threshold. The automatic test for frequency discrimination is performed by means of a modified automatic audiometer at fixed frequencies, each administered for a duration of 60 s. The test involves the stimulus of a series of pairs of tone bursts of 500 ms duration: the frequency of one of the tone bursts (f0) is constant, while the other (f0 + delta f) gradually increases and decreases according to the subject's response. The tracings obtained facilitate the evaluation of the discrimination capability of the subject. The pattern obtained from a sample of normally hearing people was analysed in order to …
Hearing loss and use of health services : a population-based cross-sectional study among Finnish older adults
2015
Background Older adults with hearing difficulties face problems of communication which may lead to underuse of health services. This study investigated the association of hearing loss and self-reported hearing difficulty with the use of health services and unmet health care needs in older adults. Methods Data on persons aged 65 and older (n = 2144) drawn from a population-based study, Health 2000, were analyzed. Hearing loss was determined with screening audiometry (n = 1680). Structured face-to-face interviews were used to assess self-reported hearing difficulty (n = 1962), use of health services (physician and nurse visits, health examinations, mental health services, physical therapy, he…
Hearing among 75-year-old people in three Nordic localities: A comparative study
2005
The aim of this study was to compare auditory functions and to analyse the prevalence of hearing impairment and the relationship of self-reported hearing disability with audiometric test results among 75-year-old people in three Nordic localities. The representative samples came from Glostrup, Denmark (n = 571), Goteborg, Sweden (n =450), and Jyvaskyla, Finland (n =388). The median pure-tone thresholds were rather similar in all three populations. The prevalence of moderate hearing impairment varied between 26% and 34% in men, and between 17% and 23% in women. The corresponding figures in the prevalence of self-reported hearing difficulties were 41%-57%, and 28%-37%. The self-reported diffi…
